The mobile device has connectivity to the infrastructure while the disconnected device has no connectivity to the infrastructure. The mobile device receives from the user a selection of the disconnected device in a list of disconnected devices, determines a location of the mobile device, and determines whether the mobile device is in proximity to a predefined location of the disconnected device. The mobile device invokes passive listening to a sound generated by the disconnected device. The mobile device determines whether the sound can be detected. The mobile device steams audio with information of a location of the mobile device to the audio analysis system. The mobile device receives a notification of the operation status of the disconnected device.

BACKGROUND

The present invention relates generally to a mobile device and an infrastructure or cloud computing environment, and more particularly to monitoring a status of a disconnected device by a mobile device and an audio analysis system in an infrastructure or cloud computing environment.

In the Internet of Things (IoT), physical devices, referred to as connected devices or smart devices, are connected in the inter-networking. The connected devices or smart devices are embedded with electronics, software, sensors, actuators, and network connectivity, so that these connected devices or smart devices are enabled to collect and exchange data. The status of these connected devices or smart devices can be reported to mobile devices such as smartphones. For example, a smart thermometer can track the temperature of food on a grill and send an alert to a mobile device such as a smartphone when the food reaches a certain temperature or cooking is finished. There are typically two means of connectivity for smart devices. First, smart devices with built-in cellular connectivity are connected to the cloud directly. Second, smart devices are paired to a cloud connected device; for example, the connectivity is established by creating a Bluetooth® connection between a smart device and a mobile device such as a smartphone. (Bluetooth is a trademark of Bluetooth Special Interest Group.)

However, many devices have no means of connectivity to the cloud and they are disconnected devices or non-smart devices. The disconnected devices or non-smart devices include appliances such as washing machines and dishwashers. The disconnected devices or non-smart devices also include smoke alarms. Many kitchen gadgets such as toasters are the disconnected devices or non-smart devices.

DETAILED DESCRIPTION

Embodiments of the present invention disclose a system and method for monitoring a status of a disconnected device or non-smart device by a mobile device and an audio analysis system in a cloud infrastructure or cloud computing environment. The disconnected device or non-smart device has no means of connectivity to the cloud infrastructure or cloud computing environment, while the mobile device has connectivity to the cloud infrastructure. In the system and method, a mobile device (such as a smartphone) uses passive listening and a location service on a mobile device to determine whether a disconnected device (such as a washing machine) is emitting sounds. The cloud-based audio analysis system analyzes the sounds emitted by the disconnected device and determines the status of the disconnected device. Based on a predetermined event, the cloud-based audio analysis system issues a notification to the mobile device.

FIG. 1 is a diagram illustrating system 100 for monitoring a status of disconnected device 120 by mobile device 110 and audio analysis system 130 in cloud infrastructure 140, in accordance with one embodiment of the present invention.

Disconnected device (or non-smart device) 120 has no connectivity to cloud infrastructure 140. Disconnected device (or non-smart device) 120 may be an appliance such as a washing machine or a dishwasher. Disconnected device (or non-smart device) 120 may be, for example, a smoke alarm. Disconnected device (or non-smart device) 120 may be a kitchen gadget such as a toaster.

Mobile device 110 has connectivity to cloud infrastructure 140. For example, mobile device 110 is a smartphone. The smartphone, as a mobile computing device, has an operating system that is capable of running computing programs. The mobile computing device is described in more detail in later paragraphs with reference to FIG. 3 which illustrates components of a computing device.

In embodiments of the present invention, audio analysis system 130 is in cloud infrastructure 140. In one embodiment, audio analysis system 130 resides on a physical machine as a server in cloud infrastructure 140. The physical machine hosting audio analysis system 130 is a computing device which is described in more detail in later paragraphs with reference to FIG. 3. In another embodiment, audio analysis system 130 resides on a virtual machine or another virtualization implementation as a server in cloud infrastructure 140. The virtual machine or the virtualization implementation runs on a physical machine.

A mobile app running on mobile device 110 is defined to passively listen to the operation of disconnected device 120. A user of mobile device 110 specifies a list of disconnected devices (including disconnected device 120) and locations of the disconnected devices. For example, the user may specify that mobile device 110 passively listens to sounds from a laundry machine when the user is located near to a laundry room in a home. The mobile app on mobile device 110 uses a location service on mobile device 110, such as GPS and/or Beacons, to determine a current location of mobile device 110. When mobile device 110 is located at or near a predefined location of disconnected device 120 (such as the laundry machine in the laundry room), the mobile app invokes passive listening. The passive listening uses a microphone on mobile device 110 to automatically record audio. The passive listening is the same technology used by services such as “Hey Siri” on iOS, “Alexa” on Amazon, and “OK Google” on Android.

The mobile app on mobile device 110 analyzes passively recorded audio and determines whether the sound of disconnected device 120 can be detected. For example, when mobile device 110 is near the laundry room, mobile device 110 determines whether sound of the laundry machine be detected. When the sound of disconnected device 120 is audibly picked up by mobile device 110 or mobile device 110 determines that the sound of disconnected device 120 can be detected, mobile device 110 streams the audio with the information of the current location of mobile device 110 to audio analysis system 130 in cloud infrastructure 140, using network connectivity capabilities of mobile device 110.

In response to receiving the streamed audio with the information of the current location of mobile device 110, audio analysis system 130 determines from which specific one of disconnected devices the audio is recorded, based the information of the current location of mobile device 110. Audio analysis system 130 pairs the location of mobile device 110 and the predefined location of a specific of the disconnected devices. The information of predefined locations of different disconnected devices is stored in a knowledge base in cloud infrastructure 140. If audio analysis system 130 pairs the location of mobile device 110 with the predefined location of the specific one (e.g., disconnected device 120) of the disconnected devices, audio analysis system 130 can determine that the audio is recorded from the specific one (e.g., disconnected device 120) of the disconnected devices. For example, if audio analysis system 130 can pair the current location of mobile device 110 and the location of a washing machine in the laundry room, audio analysis system 130 can then determine that the audio recorded by mobile device 110 is from a washing machine instead of others such as a dishwasher.

Audio analysis system 130 analyzes the audio recorded and streamed by mobile device 110 and compares the recorded audio with various known sounds of disconnected device 120. The various known sounds (pre-recorded) of disconnected device 120 are stored in the knowledge database in cloud infrastructure 140. Based on a comparison of the audio and the various known sounds of disconnected device 120, by matching the audio with one of the various known sounds of disconnected device 120, audio analysis system 130 determines an operation status of disconnected device 120. For example, audio analysis system 130 compares the audio of a washing machine to washing machine's various sounds stored in the knowledge database. The washing machine's various known sounds are sounds for different operation cycles. By matching the streamed audio with one of the washing machine's various known sounds, audio analysis system 130 determines an operation cycle of the washing machine (such as a spin cycle, a soak cycle, etc).

Audio analysis system 130 updates the operation status in the knowledge database in cloud infrastructure 140. The user can check the operation status updated in the knowledge database in cloud infrastructure 140. For events predetermined by the user, audio analysis system 130 sends notifications to mobile device 110. For example, completion of operation cycles of the washing machine is an event predetermined by the user; when audio analysis system 130 determines that the washing machine's cycles complete, audio analysis system 130 sends a notification of the completion to mobile device 110.

FIG. 2 is a flowchart showing operational steps for monitoring a status of disconnected device 120 by mobile device 110 and audio analysis system 130 in cloud infrastructure 140, in accordance with one embodiment of the present invention. At step 201, mobile device 110 receives from a user a selection of disconnected device 120 in a list of disconnected devices. At step 202, mobile device 110 determines a location of mobile device 110. A mobile app on mobile device 110 uses a location service on mobile device 110 to determine the current location of mobile device 110. For example, the location service on mobile device 110 is GPS or Beacons.

At step 203, mobile device 110 determines whether mobile device 110 is in proximity to a predefined location of disconnected device 120. In response to determining that mobile device 110 is in proximity to the predefined location of disconnected device 120, at step 204, mobile device 110 invokes passive listening of mobile device 110 to a sound generated by disconnected device 120. A mobile app on mobile device 110 invokes passive listening. For example, the passive listening uses a microphone on mobile device 110 to automatically record audio.

At step 205, mobile device 110 analyzes audio recorded during the passive listening to determine whether the sound can be detected by mobile device 110. In response to determining that the sound can be detected by mobile device 110, at step 206, mobile device 110 streams the audio with information of the location of mobile device 110 to audio analysis system 130 in cloud infrastructure 140.

In response to receiving the streamed audio with the information of the location of mobile device 110, at step 207, audio analysis system 130 determines whether the audio is recorded from disconnected device 120, based on the information of the location of mobile device 110. To determine from which one of disconnected devices the audio is recorded, audio analysis system 130 pairs the location of mobile device 110 and the predefined location of the one of the disconnected devices. The information of the predefined locations of the disconnected devices is stored in a knowledge base in cloud infrastructure 140. Audio analysis system 130 determines the audio is recorded from disconnected device 120, if the location of mobile device 110 matches the predefined location of disconnected device 120.

In response to determining that the audio is recorded from disconnected device 120, at step 208, audio analysis system 130 analyzes the audio (which is streamed form mobile device 110) and compares the audio with pre-recorded sounds of disconnected device 120. The pre-recorded sounds of disconnected device 120 are generated in different operation statuses of disconnected device 120 and stored in the knowledge base in cloud infrastructure 140.

At step 209, audio analysis system 130 determines an operation status of disconnected device 120, based on a comparison of the audio and the pre-recorded sounds of disconnected device 120. Audio analysis system 130 makes the determination of the operation status by matching the audio with one of the pre-recorded sounds of disconnected device 120. At step 210, audio analysis system 130 updates the operation status of disconnected device 120 in the knowledge database.

At step 211, audio analysis system 130 sends to mobile device 110 a notification for an event predetermined by the user of mobile device 110. A predetermined event is a certain operation status for the user receiving the notification from audio analysis system 130. At this step, in response to determining that the operation status determined at step 209 is the event predetermined by the user of mobile device 110, audio analysis system 130 sends to mobile device 110 the notification of the operation status. For example, if completion of an operation of disconnected device 120 is an event predetermined by the user, audio analysis system 130 sends a notification of the completion to mobile device 110 when audio analysis system 130 determines that the operation of disconnected device 120 completes.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 4, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices are used by cloud consumers, such as mobile device 54A (for example mobile device 110 as shown in FIG. 1), desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 4 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 5, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 4) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 5 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:

Hardware and software layer 60 includes hardware and software components. Examples of hardware components include: mainframes, RISC (Reduced Instruction Set Computer) architecture based servers, servers, blade servers, storage devices, and networks and networking components. In some embodiments, software components include network application server software and database software.

Virtualization layer 62 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers, virtual storage, virtual networks, including virtual private networks, virtual applications and operating systems, and virtual clients.

In one example, management layer 64 may provide the functions described below. Resource provisioning provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may include application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User Portal provides access to the cloud computing environment for consumers and system administrators. Service Level Management provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) Planning and Fulfillment provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.

Workloads layer 66 provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: Mapping and Navigation, Software Development and Lifecycle Management, Virtual Classroom Education Delivery, Data Analytics Processing, Transaction Processing, and functionality according to the present invention (Function 66 a).
